Figure 1 The molecular structure of the title compound. Displacement ellipsoids are drawn at the 50% probability level. The intramolecular N—H⋯O hydrogen bond is shown as a dashed line. For clarity reason the atoms (C13, C13a, F1, F1a, F2, F2a, F3 and F3a) of the trifluoromethyl groups are not labeled. |
